It's not just Joe Biden's age. It's not just his debate debacle, which made the president look slow, old, foggy. It's what's next that truly worries even Biden's biggest supporters.
- They fear that if three years as president took this much of a toll, Biden could look, act, sound and feel much worse at 86, after five more years. And Democrats would be devastated if Donald Trump won because voters concluded Biden's time has passed.
Why it matters: Top Democrats worry Biden's situation hits too close to home for too many to ignore. Most people have watched a loved one decline — at first slowly, then dramatically — as they hit their mid-80s. These Democrats fear the party, not just Biden, would pay for ignoring this.
